Title: Improvements in d.c. motors for clocks
IPC: G04C3/16
Filed: 1964-05-15
Abstract: 1,021,270. Clocks. KIENZLE UHRENTABRIKEN G.m.b.H. May 15, 1964 [May 22, 1963], No. 20323/64. Heading G3T. [Also in Division H2] Current in stator winding 3 of an electric motor, used to tension the mainspring in a clock, is switched on and off by the sealed, magnetically operated, switch 1 when the direction of the permanent magnet field reverses with rotation of rotor 2<SP>1</SP>, 2<SP>11</SP>. The field strength of the rotor magnets is insufficient to operate the switch without the additional field of magnet 4 which is movable in dependence on the state of winding of the mainspring towards (spring unwound) and away from (spring wound) the switch to start and stop the motor. In a modification two stator coils are used and are controlled in a similar manner by two switches. A zener diode may be used in parallel with the power supply to prevent overvoltages and R-C networks used to obtain rapid de-energization of the stator windings. <SP>*</SP>
Patent GB-205317-A (GB)
Abstract: 205,317. Refractories Machinery Manufacturing Co., and Norton, C. L. Oct. 2, 1922. Endless-chain machines; delivery.-Comprises means for bringing a series of pallets successively into exact alignment with corresponding moulds to receive the bricks discharged therefrom. The invention is illustrated in connection with the machine described in Specification 162,423, in which moulds 17 are attached to endless chains 13 passing, at the delivery end, over sprockets 6. Endless chains 33 passing around driving-sprockets 32 carry a series of pallet holders 37 furnished with lugs 45 adapted to be engaged by projections 27 on the moulds as they pass around the sprockets 6, the holders being supported around the sprockets by flexible guides 58 leading to horizontal guide rails 60 disposed beneath the lower run of the moulds. During passage of the rails 58, 60, the holders 37 are aligned with and driven by the moulds through the parts 27, 45, the chains 33 hanging loosely, as shown. The sprockets 32 co-operate with brake devices 75, Fig. 3, at the discharge point to return the holders 37 to the sprockets 6, Fig. 2, at the correct speed. Weighted hooks 47 hold back the holders 37 until engaged by a mould. The holders 37, Fig. 10, comprise a shallow receptacle to receive a plain pallet 41 and are provided with off-set portions 43 carrying the projections 45. After passing over the sprockets 32, Fig. 2, the pallets are retained within their holders by a weighted lever 52 or by hanging chains 57 bearing upon the face of the pallets. As the holders traverse the rails 60, the bricks are ejected on to the pallets by upward movement of the moulds by rails 16, Fig. 3, relatively to ejectors held down by rails 62. After ejection, the loaded holders pass down rails 61, where the pallets and bricks are lifted out by fingers 80 and pass on to a table 79, the holders passing back to the sprockets 33 where they receive fresh pallets. To reduce friction, the holders may be supported along the guides 58, 60 by endless cables.

Title: Improvements in wheel slip detectors for an electrically propelled vehicle
Inventor: GRAHAM GERALD WALLACE
IPC: B60L3/10
Filed: 1963-05-23
Abstract: 1,080,843. Transistor circuits; gating circuits. ENGLISH ELECTRIC CO. Ltd. May 21, 1964 [May 23, 1963], No. 20572/63. Headings H3B, H3P and H3T. [Also in Divisions G1 and H2] An electric circuit comprises: means responsive to a number of input signals for producing a first intermediate signal proportional to the magnitude of the largest input signal; means producing a second intermediate signal proportional to the average of the input signals; and means producing an output signal proportional to the difference between the two intermediate signals. The arrangement is applied to the detection of wheel slip in an electrically propelled vehicle having a number of wheels driven independently by separate electric motors. In a first embodiment, Fig. 1, conductors 10 . . . 13 carrying the current of four electric motors form the primaries of four D.C. transformers which produce outputs at terminals 25 and 26, 27 and 28, 29 and 30, 31 and 32 respectively. Each pair of output terminals is connected to a winding W1 . . . W4 on a magnetic amplifier and the input terminals of a bridge rectifier R1A . . . R4A respectively, the output terminals of bridges R1A . . . R4A being connetted in series with a winding W5 on the magnetic amplifier. If all the currents through windings W1 . . . W4 are equal a current of the same magnitude will flow through winding W5 and, if the number of turns on winding W5 is four times the turns on windings W1 . . . W4, the resultant magnetomotive force is zero. If it is now assumed that one of the currents increases, a greater current will flow through winding W5 and will maintain the rectifiers in the bridges R1A . . . R4A conducting, so that the other currents in the windings W1 . . . W4 can flow back to the supply without passing through winding W5. A net magnetomotive force is thus produced resulting in an output signal being fed to load 43, indicating wheel slip. This signal may be used to actuate an indicator or vary the motor supply. Alternatively the motors may be controlled by a servo S in series with winding 5. The gain of the magnetic amplifier may be increased by closing switch 42. In a second embodiment, Fig. 2, the outputs from each D.C. transformer is fed to an individual resistor 74 and a common resistor 76, resistors 74 being four times resistor 76. With all four inputs equal the voltage across each resistor 74 is equal to that across resistor 76 and transistor TR1 is cut off. If one of the inputs increases the voltage across the associated resistor 74 increases and transistor TR1 conducts to produce an output at terminal 81.

Title: Formation of twisted thread assemblies
IPC: D02G3/28
Filed: 1971-04-19
Abstract: 1336932 Twisted threads COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 19 April 1971 [9 Feb 1970] 21446/71 Headings DID D1F DIN and DIW  A method of forming a twisted thread assembly from at least two textile strands 6 comprises twisting a strand so that it has repeated along its length alternating zones of opposite twist and converging the twisted strand with another strand and allowing it to twist around that other strand to form a twisted thread assembly 11, and the method is characterised by engaging the converged strands with a surface which does not prevent the assembly of strands from rotating at the position of engagement with the surface but does inhibit separation of the converged strands under the influence of ballooning forces generated by rotation of the strands as they twist ply together. In a preferred embodiment, a plurality of strands 6 are fed to a pair of reciprocating strand twisting rollers 3, 4, where alternating zones of opposite twist are imparted to the strands. The strands 6 after passing the nip of the rollers 3, 4, which are preferably rubber covered, are brought together in pairs at converging guides 8. One strand in each pair is passed round a phasing guide 7 to bring about the desired phasing between the strands to be converged. The converged strands twist about one another and are passed through guides 9 in a pivoted plate 13, and thence to guides 10 before passing to a package winding station. During threading-up of the apparatus the plate 13 is swung about hinge 14 and the yarn 11 assumes a direct line path from the convergence guide 8 to the guide 10. The plate 13 is then swung back into position and so engages the yarn 11 and pulls it out of the direct line path. The plate may be replaced by a surface which engages the converged strands as they travel in a straight line path and extends over a part of that path. The surface may be provided with grooves to receive the yarns. Alternatively tubular guides or open channels could engage the yarns over straight lengths to prevent ballooning.
